PROG

(Scheme function implementing this automorphism on list-structures:)

(define (gmA073206 s) (cond ((pair? s) (gmA073206 (car s)) (gmA072797! s) (gmA073206 (cdr s)) (gmA072796! s))) s)

CROSSREFS

Inverse permutation: A073205. The car/cdr-flipped conjugate of A073195, i.e. A073206(n) = A057163(A073195(A057163(n))). Cf. also A073207-A073210.

The scheme functions gma072796! and gma072797! referred to below are given in A072796 and A072797.

Sequence in context: A085163 A084469 A085166 * A125987 A073198 A071661

Adjacent sequences:  A073203 A073204 A073205 * A073207 A073208 A073209
